Martin Logan reQuests vs newer Martin Logan offerings

The woofer/bass integration with the stat panels has been markedly improved with their latest higher end models.  Another big PLUS has been the addition of Anthem Room Correction, for optimizing overall bass response for your particular room and setup.

That said, the ML Request was/is still an excellent speaker, with a slightly larger stat panel than many of the newer models.  If the panels and woofers are still in good shape, you could add a separate ML BalancedForce sub (with the appropriate downloaded profile matching the Request), and be quite happy with the result.

Cool good info..  But you're saying ML comes with ARC?  My Anthem amp has ARC already.  I'm assuming it's the same.

Yes, it's essentially the same.  With ML speakers, it's used only for optimizing the bass response. 

I suggest posting your question over at http://www.martinloganowners.com/forum/ if you'd like more responses.
